Plant Somatic Embryo Sorting via Fluid Stirring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The somatic embryogenesis process for producing genetically identical plants is laborious and inefficient, particularly in the subjective selection and manual transfer of somatic embryos to germination medium, which limits production scale and requires expensive instrumentation for objective evaluation.
Innovation Solution
A method involving stirring a plurality of plant somatic embryos in a fluid to sort them according to germination potential, dispensing them over time based on this potential, and depositing them on a substrate, which simplifies the selection process and increases production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual evaluation and selection of embryos is performed, then subjective criteria can be applied to select desirable embryos, but the process becomes laborious, time-consuming, and subject to human error
Solution Approach 1:
The patent replaces manual visual evaluation with automated image analysis systems that use cameras and computational algorithms to assess embryo morphology, size, and development stage. This substitution eliminates human labor while maintaining or improving selection accuracy through objective digital measurement and classification algorithms.
Solution Approach 2:
The patent creates digital copies (images) of embryos for analysis, allowing repeated examination and classification without physically handling each embryo. The image data serves as a copy that can be processed by software to automatically identify and sort desirable embryos, replacing the need for manual inspection.
2Ease of operation
If manual transfer of selected embryos to germination medium is performed, then individual embryo handling is possible, but the process remains tedious and laborious
Solution Approach 1:
The patent replaces manual embryo transfer with automated robotic systems or fluid-based transfer mechanisms that can handle multiple embryos simultaneously. This automation maintains precise control over embryo placement while dramatically increasing throughput and eliminating the tedious nature of manual handling.
Solution Approach 2:
The patent employs fluid-based systems (pneumatic or hydraulic) to transport and deposit embryos onto germination medium. These fluid-based mechanisms can handle large numbers of embryos efficiently, providing both ease of operation and high productivity by eliminating manual pick-and-place operations.
3Measurement precision
If expensive instrumentation for objective embryo evaluation is used, then classification accuracy improves, but the cost and complexity of the system increases
Solution Approach 1:
The patent uses simple digital image copying rather than complex instrumentation to capture embryo characteristics. Standard cameras and image processing software provide sufficient accuracy for classification without requiring expensive specialized equipment, thereby reducing system complexity and cost while maintaining measurement precision.
Solution Approach 2:
The patent changes the approach from using expensive physical instrumentation to using software-based parameter analysis of digital images. By transforming the evaluation into a computational problem rather than a physical measurement problem, the system achieves high accuracy with minimal hardware complexity and reduced cost.
4Productivity
If large numbers of embryos are produced through asexual propagation, then production scale increases, but the laborious selection process becomes a major production bottleneck
Solution Approach 1:
The patent applies automated image analysis and classification systems that can rapidly evaluate large numbers of embryos simultaneously. This automation eliminates the time-consuming manual selection process, allowing high-volume production to scale effectively without being bottlenecked by laborious individual embryo assessment.
Solution Approach 2:
The patent implements continuous automated screening and selection processes that operate without interruption. Rather than processing embryos in batches through manual inspection, the system continuously images, analyzes, and sorts embryos, maintaining constant productive action and eliminating idle time associated with manual operation transitions.
